Ludwigshafen, Germany - BASF's Colo-Fast WST, a polyurethane glass encapsulation spray, is being put to good use in panoramic automotive windscreens, the chemical company said in a 9 June statement.
The PU window spray for large-area windows creates flush seals around the windscreens, BASF said, adding that it is currently being used in Opel's Astra GTC.
The Astra GTC's windshield is 1.5 metres long, amounting to more than a third of the vehicle's total length, and BASF said its light-stable Colo-Fast systems helped to achieve this size. The company also said that window spray technology allowed for greater design freedom, while the reaction time of less than 45 seconds and reduced reworking improves production efficiency and so cuts investment costs.
Belgian glass supplier Splifar is the first company to be granted a licence by BASF for Colo-Fast WST technology and to invest in a production installation. Production with this light-stable PU system has been underway since the end of 2010.
BASF said sights are now set on the future projects, such as large, complex windows of laminated or toughened safety glass for cars and commercial vehicles and that is already involved in plans for a windshield for an unnamed truck manufacturer.
